Signaling capacity utility for modeling 5G Steering of Roaming (SoR) overhead, calculating the UDM SoR container delivery load and NAS transport burden for inbound roaming users.
Roaming SoR modelers estimate steering efficacy and signaling/OTA cost so operators can improve visited-network mix without breaking attach success.
The analyzer uses the SoR procedure model from 3GPP TS 23.501 to quantify the UDM-to-AMF N8 interface load and the NAS DL NAS Transport message rate generated by SoR container delivery to active roamers.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
SoR (Steering of Roaming) is a mandatory 5G SA security feature allowing the HPLMN to send a signed list of preferred PLMNs to the UE. High roamer volumes can generate significant signaling load if SoR is triggered frequently.

Raising signaling-based steering intensity may lift preferred-network share 8% while doubling LU rejects—net margin can fall if wholesale penalties apply.
Market-specific IR.21 and device behavior vary widely.
SoR techniques influence which VPLMN a UE prefers while roaming, using signaling and/or OTA methods to improve margin and quality.
Compare targeted vs achieved visit distribution, steering success rate, and incremental signaling/OTA cost against revenue uplift.
Yes—failed registrations and ping-pong between networks increase attach signaling and complaints. Model cost of failures, not only steered share.
